WOW technology in High Density Impact Zones to reduce shock and abrasion

While I know many athletes that compete while wearing compression socks, that hasn't worked for me yet - can't get the right thickness in sock and have my shoes fit right. However, these PhD Compression Socks are the first thing I reach for after a long day on the trails. Their skin-tight fit provides an almost massaging effect on my tired calves. One of my favorite uses is to wear these during travel! Whether in a car or on a plane for several hours, they keep the blood flowing and my legs don't feel nearly as wasted once I reach my destination.
